One end of the central movable shaft is provided with an external thread, the movable shaft is provided with a cavity near the other end, and the inner wall of the cavity is provided with a screw with the external thread a threaded end, the externally threaded end of the central movable shaft is screwed in from the other end of the movable shaft, and the other end of the central movable shaft is fixedly connected to the end surface of the hand wheel, and the outer sleeve is sleeved in the a linear bearing is disposed between the outer sleeve and the movable shaft, and a locking cover is disposed at one end of the outer sleeve near the movable tip, and a lock nut is disposed at the other end. A locking cover and a lock nut are used to lock the special movable top of the engraving machine on the engraving machine.

Further, a bearing I is disposed between the movable shaft and the movable tip.

Specifically, the number of the bearings I is three, and an inner ring sleeve and an outer ring sleeve are disposed between the third and the first two.

Further, the locking cover is fastened on the outer sleeve, and an inner surface of the locking cover is in contact with an outer surface of the linear bearing.

Specifically, the inner ring of the locking cover is provided with a stop, and an outer surface of the movable shaft is provided with a groove that cooperates with the opening, and the opening is caught in the groove.

Further, the lock nut is fastened to one end of the outer sleeve, and a bearing II is disposed between the lock nut and the central movable shaft.

Specifically, the number of the bearings II is two.

Further, the hand wheel is coupled to the central movable shaft by a flat key.

The utility model has the beneficial effects that the existing movable top is directly connected with the movable shaft by the outer sleeve, and the direct connection between the two is easy to cause shaking, and the limiting screw is arranged on the circumferential surface, which is not easy to lock and easily causes the movable shaft to deform together and is eccentric. The invention adopts a linear bearing to connect the outer sleeve and the movable shaft, thereby eliminating the gap between the two to make the connection more stable, and further setting the locking screw to the end surface of the hand wheel, the locking effect is stronger and safer.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

As shown in FIG. 1 and FIG. 2, a special activity top for an engraving machine includes a movable shaft 2, a central movable shaft 10, an outer sleeve 3, a movable top 5 and a hand wheel 12, and the movable top 5 is set in the center. The movable shaft 2 is provided with an external thread at one end of the movable shaft 2, and the movable shaft 2 is provided with a cavity near the other end, and the inner wall of the cavity is provided with an internal thread matched with the external thread.
